Tata Power-DDL and Norway’s PIXII Join Hands To Explore Applicability of Distributed Pole-Mounted Storage SystemsDate : Jan 08, 2019

  • Project to improve health of distribution network by significantly reducing technical losses and investment needed to support fast-growing Indian urban landscape
  • Will augment overall network integrity for addition of renewables and other distributed energy resources to distribution grid
  • MoU Signed on the occasion of the state visit of Hon’ble Prime Minister of Norway, Ms. Erna Solberg during India-Norway Business Summit 2019 at New Delhi

India’s pioneer power distribution company -Tata Power Delhi Distribution (Tata Power-DDL) and Norwegian power technology company PIXII have joined hands to explore the use of distributed pole-mounted storage for a resilient and sustainable distribution grid. The MoU for the collaboration was signed between Mr. Sanjay Banga, CEO, Tata Power-DDL and Mr. Ole Jakob Sørdalen, Chief Innovation Officer PIXII on the occasion of the state visit of the Hon’ble Prime Minister of Norway Ms. Erna Solberg during the India-Norway Business Summit 2019 at New Delhi, India.

India is witnessing a major revamp of its electricity generation system and distribution network with the urgency to leverage renewable energy generation and emerging smart grid technologies to make its energy supply system smart and green. As a natural progression from distributed solar PV/grid level battery storage, distributed pole-mounted storage is yet another emerging technology that has the potential to facilitate smart optimization of distribution ecosystems by ensuring various aspects of grid reliability.

As a pioneering distribution company, Tata Power-DDL is in the process of integrating Indian’s first 10MW of grid storage to address grid stress situations and to compensate variability with renewable generation. As an extension to this effort, the company is evaluating pole-mounted storage solutions to address the challenge of space constraints to bring a reliable and a robust grid for customers and communities.

With this distributed storage, Tata Power-DDL aims to reduce the strain on distribution transformers by smoothening the daily electricity peaking cycle. The integrated system will also help reduce technical losses and improve the asset health of feeders and distribution transformers, thus significantly reducing network augmentation investment needed to support a fast-growing urban landscape.

This exploratory pilot project will help Tata Power DDL to improve overall network integrity and support addition of renewables and other distributed energy resources to the distribution grid.

Speaking on the collaboration, Mr. Sanjay Banga, CEO Tata Power DDL said, At Tata Power DDL, we are constantly looking for innovative technologies to promote smart sustainable solutions that can be integrated with our grid and eventually with grids across the country. We are excited to partner with PIXII to explore pole-mounted storage cost effective solutions.

Mr. Ole Jakob Sørdalen, Chief Innovation Officer, PIXII said, As a future oriented technology provider, we are very excited about the collaboration with an innovation oriented organization like Tata Power-DDL. We are looking forward to contributing to a greener, more cost-effective, and reliable grid together with Tata Power-DDL.

About Tata Power-DDL

Tata Power Delhi Distribution Limited [Tata Power-DDL] is a joint venture between Tata Power and the Government of NCT of Delhi with the majority stake being held by Tata Power Company (51%). Tata Power-DDL distributes electricity in North & North West parts of Delhi and serves a populace of 7 million. With a registered consumer base of 1.6 million and a peak load of around 1960 MW, the company's operations span across an area of 510 sq. KMs. Tata Power-DDL has been the frontrunner in implementing power distribution reforms in the capital city and is acknowledged for its consumer friendly practices. Since privatization, the Aggregate Technical & Commercial (AT&C) losses in Tata Power-DDL areas have shown a record decline. AT&C loss is a measure of overall efficiency of the distribution business which is the difference between units input into the system and the units for which the payment is collected. Today, AT&C losses stand at 8.5 % which is an unprecedented reduction of around 84% from an opening loss level of 53% in July 2002.


PIXII is a power technology company headquartered in Norway that develop solutions for power conversion and energy storage. PIXII has decades of experience in design, manufacturing and sales of modular power conversion solutions, bringing a new level of flexibility to energy storage solutions. PIXII develops technologies that enable smart power flexibility that contributes to clean, cost-effective and reliable electricity for all.
